Qualcomm is demonstrated on video technology features fast charging Quick Charge 2.0.According to the manufacturer, it allows you to charge the battery standard capacity in half an hour by 60%.
Quick Charge is based on the Snapdragon chip and can significantly accelerate the process of charging compatible electronics. To show a clear example, Qualcomm released video, which compares the performance of charging Quick Charge 2.0 with two analogues.
The video shows three identical smartphone Nexus 6 Battery capacity 3200 mAh. To each of the devices connected to its charge: to the extreme left - 5V / 1A, the middle - 5V / 2A, and to the far right - Quick Charge 2.0 (5V / 3A). Last phone charges with 0% to 50% in just 40 minutes. During this same period of time the first smartphone charge on 22%, the second - 32%. Thus, charging through the Quick Charge 2.0 was more than two times faster than via a cable 5V / 1A.
"Inside the smartphone has the power controller, which regulates the energy available to him and protects against overcharging, - said the representative of Qualcomm, - Controller controls the parameters of the battery and how many can take the battery. For fast charging requires a special network adapter, which, in addition to voltage converter has a controller that determines whether a device supports fast charging. "
Already, Quick Charge 2.0 supports about 15 models of smartphones and tablets - Sony, Samsung, Motorola, HTC, Nexus, there is a pair of tens and road network adapters, which, however, users have to buy separately.
